[填空题]Many Benefit from Cancer Organization
1. Do you know a child who survived leukemia Do you have a mother, sister or aunt whose breast cancer was found early thanks to a mammogram Do you have a friend or coworker who quit smoking to reduce their risk of lung cancer Each of these individuals benefited from the American Cancer Society’s research program.
2. Each day scientists supported by the American Cancer Society work to find breakthroughs that will take us one step closer to a cure. The American Cancer Society has long recognized that research holds the ultimate answers to the prevention, diagnosis and treatment of cancer.
3. As the largest source of nonprofit cancer research funds in the United States, the American Cancer Society devotes over $100 million each year to research. Since 1946, they’ve invested more than $2.4 billion in research. The investment has paid rich dividends: In 1946, only one in four cancer patients was alive five years after dia

[单项选择]How many times do you wake during the night Do the slightest disturbances—the sound of a toilet flushing, or the TV in the next room—rouse you from sleep, while your partner slumbers soundly through a thunderstorm
It turns out that some people’s brains are better than others’ at blockading (阻碍) the constant incoming flow of environmental stimuli during sleep, and in a new study, scientists have identified and measured the process. They hope that one day they will be able to manipulate this ability in order to give lighter sleepers a better night’s rest.
Ambient (周围的) sound is the most common cause of sleep interruption, since even during sleep the brain must actively receive sensory information. But as it continually monitors stimuli (刺激) from the environment in order to protect against threats, the brain also actively blockades them to allow body and mind to recharge and rest during sleep. Now, for the first time, sleep researchers led by neurologist Dr. Jeffrey Ellenbogen,
A. How the brain receives sensory information.
B. Which brain area monitors stimuli from the environment.
C. How the brain finds the compromise between the two demands.
D. Which brain area allows body and mind to recharge and rest during sleep.
